6.6 Known Bugs and Limitations

• Jasper cannot be used from within applets, since Jasper relies on calling methods declared as native. This is due to a security-restriction enforced on applets by Java; they are not allowed to call native code.
• Some uses of SPTerm will leak memory on the Prolog side. This is not really a bug but may come as a surprise to the unwary. See SPTerm and Memory.
• Loading multiple SICStus runtimes has not been very well tested with multi threaded Jasper.
